I've explained my support for Joss and support against Grimes before. What I want to know is why Billy Pierce is so far behind Tiant, who may very well be elected this season. Tiant had 7 votes for 51 points last time and Pierce had nothing. Compare the two and you will see (I hope) there is little statistical difference. I don't get it. Kind of the same way I don't get why Red Faber made it in while Eppa Rixey is struggling.

Tiant will be elected without my help it seems, but he is very close on my pitcher's queue (behind Pierce). The only remarkable stat he has over the field of holdovers is a pitching WAR of 60.1 (batting WAR is -0.7). I'm having trouble figuring out where the extra (guestimate) 8-10 points comes from. Could be the ballpark... except his ERA+ is only 115. Could be the pitching age... except he pitched through the silver age of pitching, where all kinds of starting pitchers were having great years. Could be team defense... but nothing jumps out to me from those Cleveland teams of the 60s and Boston teams of the 70s as being bad. He didn't pitch particularly long for a HOF career either (77th in career BF). He's got a Gray Ink of 112 (179th all time). Yet there he is with an eqERA under 3.90 and a WAR approaching Palmer and Marichal.

I don't mean to come across as saying I do not support Tiant -- I do, or at least would be soon as a few more players are elected from my ballot. I'm showing why he's behind Joss in my queue. As well as the likes of Faber, Rixey, Ruffing, and Lemon.

... What I want to know is why Billy Pierce is so far behind Tiant, who may very well be elected this season. ... I just looked up Tiant's Hall of Merit page for the first time. The very first reply is "He looks a LOT like Billy Pierce. Was he leveraged like Pierce?"http://www.baseballthinkfactory.org/...on/luis_tiant/

There may be a plurality for Billy Pierce as the least of the Hall of Merit pitchers. Founder and "commissioner" Joe Dimino, whose research focus is Pennants Added for pitchers, has named Joe McGinnity and Bob Lemon. Officially Pierce ranks last in the 1923-1958 group, Ted Lyons to Whitey Ford.

Annually Luis Tiant is one of the best supported candidate pitchers, clearly behind only David Cone.

JW continues with the observation that
here at the Best of Baseball, Tiant leads the holdover pitchers only by pitching WAR 60.1.

(my emphasis)
That crowd does not much influence any version of WAR, whose reference point is "replacement level" play.

There is some reason to believe that the entire cohort benefited from relatively easy circumstances (as did Joss & Co. in the 19-aughts). First, they joined the major leagues soon after the second biggest permanent expansion, 1960-1962 (compare the biggest, 1899-1901). Tiant & Co. also benefited from the third biggest expansion, 1969. Second, per Craig Wright/Tom House and Bill James, pitchers benefit in longevity from physically easier work when young. The high pitching mounds and big strike zones of the 1960s major leagues provided relatively easy conditions that may have balanced or overbalanced the high numbers of starts and innings. The second point pertains only to big careers, not to big seasons.

Of course any list such as this is merely a red flag, not strong evidence for any particular problem ("bias"). It flags at least bias in WAR, bias in Best of Baseball participants, and structural bias in the Best of Baseball.

Here the likely-important aspects of "structure" are that we started in virtual 1936 and we are now in virtual 1993. Neither the 1880s cohort nor the 1960s cohort has been considered in just the same way as the 1910s cohort.
FWIW i don't believe structural bias in the BoB is important regarding the composition of that list.

So, if Pierce is at or near the bottom of elected pitchers, and Tiant is at or near the top of the holdovers, then they would have similar value right?

That crowd does not much influence WAR, whose reference point is "replacement level" play, nor TPI whose reference point is league average.

So replacement level is constant regardless of age, using normalized stats I assume?

No, replacement level is not constant.
Every measure of wins above replacement tries to measure it under particular circumstances.

"Normalize" may be a misleading term. If expansion depresses replacement level, that does make all players more valuable, except as their skills decline in concert. What should be the base for normalization, the "norm"?

From Dan Rosenheck at the Hall of Merit, I understand that the author of Baseball-Reference WAR, Sean Smith estimates replacement level W rates for groups defined by decade and fielding position, such as 1960s shortstops. In general such an approach means that the estimate "jumps" between 1959 and 1960 and then remains fixed until it jumps again between 1969 and 1970. (This is bad in principle, I don't know how bad in magnitude.)

Unfortunately I don't "know" from Dan or anyone else how Smith handles data from before and after any plausibly important change such as expansion.

Just a reminder that this election will be open only a little over another 7 hours.

We had 13 player ballots and 10 contributor ballots. We elected Roger Bresnahan, Hughie Jennings and Luis Tiant. On the contributor side, Gus Greenlee got the nod on the second tiebreaker (4 voters named him higher than Rizzuto, 4 did the opposite, so it went to how many votes each man got, and Greenlee won 6-5).
